IMPROVE!) STILL FOR ALCOHOL.

The Schedule referred to in these Letters Patent and making part of the same.

- To all whom it may concern: o

Be it known that I, ERNsT GOTTLIEB STARCK, of Chicago, in the county of Oook, and State of Illinois,

`have invented certain new and useful Improvements To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

Mylinveution relates to stills used in the production of alcohol, and consists in a novel manner of constructing and arranging the condensing-pans or head, allj as hereinafter described.

The drawing represents a vertical cross-section through a pair of pans constructed on my plan.

I construct circular pans A and B, each consisting ot' two plates-or bottoms, b and d, .concave on their upper sides, and secured within a hoop or ringi, in such manner as to leave a space between the two plates. Between the plates b and d, I place a concave plate, c, of less diameter than the hoop, so as to leave a passage up around its edges, as shown.

'Io the bottom b of the lower pan Il, I connect the large pipe D, connecting with and conduct-ing the va por from the boiler or still.

The upper plate d of pan B, and the lower plate' b of the pan A, I connect by a large pipe, E, as shown.

On the upper side of plate d of pan A, I attach another large` pipe, C, lending to the worm.

At the centre oi' the plates c, I place small pipes e, extending down the large pipes, and dipping into cups, or reservoirs i,'locatedwithin the large pipes, alittle below the bottoni oi' each pan, asshown in the drawings.

.extendoutthroughthe side of the pipe D, :is shown,

and connect it with the still, or boiler.

Near the upper edges of each of the rims t', I attach pipes n, leading down to and discharging upon the nezt pan below, as shown in the drawings.

Through the bottolnof each of theeups j' enters a The courseof the steam, or vapor is indicated by the red arrows in lthe drawing, and that of the condensed vapor, or low-wine, by the yellow arrows.

When operating the apparatus, cold water is fed on to or in the pan A, as shown by the blue lines in the drawing, and overliows; through the pipe fi, on to pan B,- and so oli-continuously.

.'lhe vapor passes from the boiler up through the pipe D, and striking against plate c, is deflected out@ ward, and `passing up past the outer edges of this plate, strikes -against plate ll, by which the heavier and grosser part is condensed.

rlhe condensed portion, or low-wine, ows down t0 the centre of plate c, and thence down, through pipe c, to reservoir f, where it overflows into pipe g, and

passes back to the boiler.

The remaining uncondensed vapor passes up pipe E to the pan, and is partially condensed, leaving pure, or nearly pure alcohol, which escapes through pipe O to the worm. Y

".lhefluid resulting from this second condensation flows down through the various pipes and' reservoiiljsto pipe h, and is carried to the boiler.

The object of the reservoirs fis to prevent the vapor from blowing through the small' pipes, as would occur did not the ends of pipesle dip below the surface of the liquid in them.

In this manner, I produce acheap and simple still, by the use of which I can producea very-pure article oi' alcohol by one distillation, instead of several, as is customary. g

Haring thus described my invention,

An improvement in apparatus for distilling alcohol,

'consisting of two or more pans, A and B, with coldwater connecting-tubes a, each having upper and lower concave bottoms, b and d, with anl intervening plate, c, provided with central tube c,also with cups f and pipe g, the whole constructed and arranged, in counection with the pipes I), E, C, and h, substantially as herein shown and described, for the purpose set forth.
